i keep getting suspended idk why

so i keep getting banned for like 12 hrs evryday once i play. i recently changed my name to something somewhat derrogetory bc i though it would be funny but i cannot change it for 3 months due to riots rules. I read all the rules and i have not violated any of them nor have i afked but all of a sudden i get banned for 12 + hrs. I would change my name but i am unable to even though i think i am getting penalized for it so there is nothing I can do and i keep getting hit with bans.
